Self-guided app-design courses—available for iPad, iPhone, and Android devices—provide 12 months of 24/7 access to resources created by Designing for the iPad author Chris Stevens and other leading app designers. Before and after computer-adaptive tests inform students of their progress during the 18 units, which include illustrated PDFs, video tutorials, step-by-step design guides, real code samples, and interactive exercises. The course generally takes 15–20 hours to complete, and students will receive certificates of completion for tests and the course.
